How to Fix Streaky Windshield Wipers — Fast!

December 9, 2021

When you're behind the wheel, a clear view of the road ahead is non-negotiable. Is your car windshield always streaky after it rains? You may need to wash your windshield, replace your wiper blades, swap out your car wash habits, or switch to a different wiper fluid. We'll teach you how to diagnose your windshield woes and how to fix streaky windshield wipers ‐ fast!

Worn or Torn Windshield Wiper Blades

If you're noticing streaks on your windshield, check your windshield wiper blades for wear and tear. Your wiper blades need semi-frequent replacing because they are created with soft rubber that naturally degrades over time.

If you're not sure when to replace windshield wipers, the general rule of thumb is to replace your wipers every 6 to 12 months. If you use your wipers frequently, they may need replacing more often.

Worn or torn rubber blades are almost guaranteed to create streaks. In addition to leaving behind streaks, chattering and squeaking are both signs you're overdue for wiper replacement. Your wipers should "hug" your windshield and move quietly and smoothly when in use.

Old or damaged wiper blades will unevenly drag pooling water droplets across your windshield ‐ resulting in streaking. Similarly, wiper arms with worn springs cause streaks because they are unevenly applying pressure to your windshield.

If your windshield wipers are worn or torn, you'll need to replace them. Be sure to check your owner's manual and select a set of wiper blades that fits your vehicle's make and model.

Dirt and Grime Accumulating on Your Windshield

Dirt, dust, road salt, dead bugs, pollen, and sap can do a number on your windshield. In any case, turning on the wipers when your windshield wiper is covered in grime will result in a streaky mess. If you see visible dirt on your windshield, it needs a good wipe down.

Here's what you'll need to get your windshield sparkling again:

• A few lint-free microfiber cloths
• Car wash
• An empty spray bottle
• A bucket
• Rubbing alcohol
• Automotive glass cleaner or white vinegar

Note: Refrain from using household glass cleaners containing ammonia on your car windshield and windows. Formulas with ammonia can damage tinted glass, create glares, and increase the likelihood of streaking.

Use the above ingredients to mix up one of these effective and popular windshield cleaner formulas.

• If you have automotive glass cleaner readily available, mix up a solution of 15% automotive window cleaner, 15% rubbing alcohol, and 70% water. Combine in a spray bottle.
• If you don't have an automotive glass cleaner, mix up this simple solution using household ingredients. DIY your car window cleaner by combining 50% rubbing alcohol, 50% water, and a capful of white vinegar in a spray bottle.

Here's the best way to clean your windshield:

• First, hose off your windshield to remove the bulk of the grime
• Fill a bucket with water, adding in some car wash. Splash your windshield with soapy water and hose off your windshield again until no soap bubbles appear
• Once your windshield has dried, spray your windshield down using your windshield cleaning formula of choice
• Using one side of your microfiber cloth, wipe your windshield in a circular motion. Swap for a clean cloth as needed
• Rubbing alcohol
• Once your windshield is free of dust and dirt, wipe your windshield down again using a clean microfiber cloth. Use circular motions to remove any remaining cleaner residue

Use this method on your front windshield, rear windshield, and car windows as needed. Be mindful of where you park now that your windshield is clean. Whenever possible, avoid parking under trees, which can release sticky sap and chalky pollen. If you can't avoid trees or frequent dusty roads, consider applying a water-repellent solution, or a window wax formulated explicitly for windshield use.

Dirt and Grime Accumulating on the Blades and in the Cowl

Dirt on your wiper blades can contribute to a streaky windshield, too! When you clean your windshield, you should also hit your windshield wiper blades and the wiper cowl.

Here's a quick rundown of how to best clean your windshield wiper blades and wiper cowl:

• Gently pull back your windshield wiper's arms
• Using your windshield cleaning solution, wipe the rubber blades and wiper arms until free of debris
• Clean out the cowl ‐ where your blades rest when not in use. First, remove large debris by hand, then clean thoroughly using your windshield cleaning solution

Cleaning your blades and cowl should help keep your view unobstructed!

Car Wash Wax Coating the Windshield

Your habit of frequenting the car wash may be to blame for your streaky windshield! It's not the soaping and sudsing that leads to streaky windshield wipers ‐ it's the car wax!

Automated car washes aren't able to tell the difference between your windshield and the body of your car, so stray wax can easily find its way onto your windshield. Over time, accumulated wax will lead to a streaky windshield ‐ and a mess that proves difficult to remove. If car wax is causing your windshield woes, follow the steps above for cleaning your windshield.

You don't need to cut out your car wash habit entirely. Instead, select a wash option without wax. If car wax is a must, elect to have it applied by hand after you clean your car.

Car Wash Wax Coating the Windshield

If you're dealing with a streaky windshield and no amount of cleaning or blade replacement is doing the trick, it may be time to swap out your wiper fluid. Wiper fluid should help you clear your windshield. However, some formulas are more likely to cause streaking because they're weak or aren't suited for some environments.

Your windshield wiper fluid likely contains water, alcohol, and some form of detergent. Depending on your daily driving conditions, you may need a formula with additives, like:

• An all-weather blend for year-round driving
• A deicing wiper fluid for snow and ice
• A bug removing wiper fluid for summer or interstate driving
• A water-beading windshield washer fluid for a rainy or foggy climate

Take care to select a wiper fluid that works well for both your car and your environmental conditions. And be sure to top off your wiper fluid tank every so often, too!
